To all whom it may concern:

Be it known that 1, JOHN J. HENRY, a citizen of the United States, residing at \Vatson, in the county of Eifingham and State of Illinois, have invented a new and useful Magazine-Firearm, of which the following is a specification.

This invention relates to magazine firearms, and has for its principal object to provide a novel form of magazine shot gun.

ith this and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of con- In the accom an in clrawin 's:Fi 'ure.

Fig. 14 is ,a side elevation of the firearm complete, parts being broken away. Fig. 15 is a side elevation of a portion of the barrel and the front end of the magazine. Fig. 16 is an end elevation looking at the nozzle of the barrel from the front end of the magazine. Fig. 17 is a detail transverse section through the receiver. Fig. 18 is a similar view showing the magazine in section and the breech end of the barrel in elevation. Fig. 19 is a side elevation of the receiver proper.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The frame 10 of the gun is provided with forwardly extending side plates 11 and 12,

and a top plate 13, the side plate 12 being preferably made removable, so that the various parts of the lock and magazine mechanism may be examined and repaired, while the plates 11 and 13 are permanently secured together in order to secure the necessary stiffness and rigidity. To the lower portion of the forward ends of the plates -11 and 12 is connected a block or collar 14 which may be permanently secured to the plates, but preferably is made detachable for the purpose of taking down the gun. For

the present, however, this collar or block 14 may be considered a part of the permanent structure, and said collar serves as a support for the magazine 15, which, also, forms a stationary part of the gun.

Above the magazine 15 is the barrel 16, the barrel being of any desired. length, and

being slidable endwise toward and from the standing breech 17. The forward end of the, barrel is provided with a dove-tailed rib 18 that fits in a correspondingly shaped groove on top of the magazine, in order to permit free longitudinal movement and prevent lateral play, while the rear end of the barrel is guided in the receiver formed by the several plates 11, 12 and 13. I

Mounted on the magazine is a forearm or I grip 20 which controls the locking mechanism, and by which the device is operated, a single forward movement of the forearm serving to move the barrel forward from the standing breech to extract and eject the empty shell and lower the carrier into position to receive a fresh shell from the magazine. Reverse or rearward movement-of the forearm serves to elevate the carriage to hold the fresh shell in alinement with the bore of the barrel to move the barrel back to receive the shell; cock the hammer and lock the barrel to the standing breech, placing the gun in readiness to fire.

To one side of the rear end of the barrel is secured a plate 23 that is provided at its upper and lower edges with ribs 24 that fit within grooves formed in the plates 12 and 13, and which serve as guides for the barrel. The opposite side of the barrel is flattened, as shown in Fig. 7, and fits against the fiat inner surface of the plate 1 1, while said plate 1 1 is provided with a longitudinally disposed groove 25 receiving a rib 26 projecting from the barrel, these parts, also, serving as barrel guides and supports. Projecting rearward from the barrel is a bar 27 that is located near the bottom and to the left of the axis of the bore, this bar having a flattened face that bears against the flat surface of the plate 11, and the upper surface of the bar is guided by a horizontally disposed shoulder 28 projecting from the plate 11, 'thus forming additional supports and guides for the barrel. This bar 27 is provided with a vertical groove 30 that is arranged to receive a locking bolt 31 that is carried by the standing breech, and when the bolt is engaged in this groove the barrel is firmly locked in place in readiness for firing.

The rear portion of the standing breech 17 is provided with parallel under- cut grooves 32 and 33 for the reception of a pair of arms 34 that are formed integral with the locking bolt 31, said bolt being of considerable width, as shown in Fig. 4, and the forward face of the bolt is inclined, as shown in Fig. 5, and is provided with a small anti-friction roller 36, so that as the bar 27 is pulled rear- Ward during the loading movement, the bolt will be pushed to the right until the groove 30 has arrived at a position to receive said bolt. The bolt is pushed to locking position by a pair of springs 37 that bear against the right hand ends of the arms 34, these springs being guided by suitable pins that project from the arms and from stationary portions of the frame. In order to permit convenient access to these parts, the arms 34 are held in position by two detachable plates 38 and 39 that form portions of the walls of the grooves 32 and 33. These plates are held in position by screws, as shown in Fig. 4, and the screws may be readily removed for the purpose of detaching the plates and permitting the removal of the locking bolt.

The movement of the bolt to release position is accomplished by a release rod 40, Fig.

6', this rod having a cam-shaped inner end 41 and being permanently secured to the forearm. When the forearm is pulled forward, the cam 41 rides against the roller 36 and than the" lugs, "so that during the forward movement of the forearm, the latter will travel to an extent sufficient to accomplish the unlocking operation before the rear walls of the grooves engage with the lugs to carry the barrel forward. In similar manner the rearward movement of the forearm to complete the reloading and'cocking would result in a preliminary movement of the forearm in advance of the barrel, but this is prevented in order that the barrel may arrive first at the closed position and before the movement of the forearm is completed.

Pivoted to the bar 27 is a lever 46 having an upwardly curved rear end which is acted upon by a leaf spring 47 tending normally to depress the rear end of the lever and elevate the forward end thereof. The forward end of the lever is arranged to move across a small groove 48 that is formed in the bar 27 at a point below the locking groove 30, (Fig. 2), and when in this position the end of the lever 46 will form a stop for the rear end of the releasing rod 40 and near the rearward or closing movement of the same the starting of the movement of the forearm on its rearward movement will engage the rear end of the rod 40 against the forward end of the lever 46, so that rod 40 will not be allowed to fully enter the groove 48. After the rod comes into contact with the lever further movement from the forearm is transmitted through this connection to the bar 27, and the barrel and its parts are carried rearward to the locking 2 position until the groove 30 has arrived in position to receive the locking bolt.

It will be observed that that portion of the bar 27 to the rear of the groove 30 is slightly inclined, so that it may engage with the inclined forward edge of the locking bolt, and with a portion of the roller 36 so that the bolt will be forced to the right against the stress of the springs 37, and the end of the release rod 40 will, therefore, be allowed to freely pass under the locking bolt. When the parts have arrived at this last mentioned position, the curved rear portion of the lever 46 engages against a pin or roller 50 that is supported by the plate 11, and the rear edge of the lever is thrown upward and its forward end downward, so as to clear the slot 48, and thus allow the release rod and'the forearm to complete their rearward movement, this being accomplished by the time the rear end of the release rod has fully entered the slot 48.

The bar 27 is provided with a rearwardly extending arm 27 which operates'as hereinafter described, for the purpose of actuating the carrier, and this bar also serves as a means for controlling the release of the shells from the magazine and their passage onto the carrier.

At the left hand side of the rear end of the magazine and extending partly within the side plate 11 is a recess 52 in which is arranged a vertically disposed pivot pin 53 carrying an escapement lever 54 having two pallets 55 and 56, the lever beingnormally held in the position shown in Fig. 10 by means of a leaf spring 57, so that the pallet 55 is in position to engage against the rearmost shell in the magazine and prevent its escape under the influence of the discharging spring which may be of the ordinary helical type, (not shown). Projecting upward from this escapement lever are two pins 58 and 59, which are arranged to be engaged by a cam 60 that projects from the forward end of the bar 27. When this bar is in the rearward position, that is to say, with the parts in readiness for firing, it will be wholly free from the pins 58 and 59, and the spring 57 will hold the pallet 55 in position to prevent the accidental discharge of a shell from the magazine, while the pallet 56 will be held clear of the bore of the magazine, so that there will be no obstruction to recharging the magazine, and shell after shell may be pushed in past the pallet 55, itbeing observed on reference to Fig. 1 that when the gun is ready for firing, the rear end of the magazine is exposed, and fresh shells may be introduced thereinto at any time.

Then the parts are moved forward for reloading, the cam 60 carried by bar 27 rides against a stationary cam 61 in the recess 52 j and then strikes against the arm or pin 59- of the escapement lever, rocking the latter,

so that the pallet 55 is moved away clear of the bore of the magazine, as shown in Fig. 11, to permit the discharge of a shell, and at the same time the pallet 56 is moved within the bore for the purpose of engaging the next succeeding shell, thus preventing the passage of more than one shell to the carrier. During the subsequent rearward movement of the bar 27 the cam 60 will ride against the arm or pin 58 for the purpose of insuring the outward movement of the latter, and the positioning of the pallet 55, so that this movement will not be wholly dependent upon the spring 57, but is made positive, the pallet being again adjusted to position to hold the shell at the rear end of the magazine.

The carrier 64 is clearly shown in Fig. 8. This carrier has an arm 65 that projects through a recess in the standing breech and is pivoted between lugs 67 on the trigger plate. The left hand edge of the arm is providedwith a recess 68 which receives a stationary guiding lug 69 projecting upward from the trigger plate, this lug serving, also as a side guide for the arm 27, and the lug operates further as a stop for limiting the outward movement of said arm 27 and the barrel. Projecting from the left hand side of the arm 65 is a flange 70 and extending upward therefrom is an inclined lug 71. The right hand side of the arm 27 has an elongated flange 72, the rear end of which forms a cam 73 and projecting from this arm is a second cam lug 74, these cams controlling and serving as the actuating. means for raising and lowering the carrier.

During the forward movement of the arm 27 the cam lug 74 engages against the arm 71 andforces the carrier downward from the position shown in Fig. 1 to the position shown in Fig. 2. During the rearward movement of the arm 27, the cam shaped end 73 of the flange 72 rides under the flange 70 of arm 65 and elevates the carrier, these two movements of the carrier being so timed as to occur while the barrel is traversing a very short distance.

The upper portion of thecarrier is trough shaped in cross section, having two vertical side walls 76 and 77, and in the top of the carrier are two cartridge lifters 78 and 79. The lifter 79 comprises a lever 80 pivoted on a pin 81 and having at its rear end a curved arm 82 that is arranged to extend under the forward portion of the shell, the arm being dished or curved to partly correspond to the contour ofthe shell. Projecting laterally from the forward end of the lever 80 is a cam arm 83 that is arranged to be engaged by a cam lug 84 projecting downward from the bottom of the rear portion of the barrel. Under normal conditions the weight of the rear end of the lever and the arm 82 is such that the arm is held down in the trough of the carrier, but when the barrel starts on its rearward movement, the cam 84 engages a cam arm 83 and the arm 82 of the lifter is elevated, thereby raising the forward end of the shell in such position that it may enter the breech end of the barrel. The lifter 78 is merely in the form of a pair of spring elevated arms having slightly inclined faces which engage the rim of the shell, these arms being connected by a suitable cross bar 85.

The side plate 77 of the carrier is rounded, forming a high flange to prevent accidental displacement of the shells or cartridges during loading.

In order to prevent accidental movement of the shell while being elevated and moved to firing position, the upper end of the magazine and the rear end of the side plate 23 are provided with projecting tongues 91 which will engage the shell in case it tends to roll from the carrier. Extending through the standing breech is a firing pin 93, the upper portion of which is grooved for the reception of a stop lug 94 that limits movement of the pin in both directions, this lug being secured to the rear face of the standing breech by a screw or other detachable connection in order to permit the removal of the pin when necessary.

The firing pin is engaged by a hammer 96 that is pivoted between lugs 97 on the trigger plate, and projecting rearward from the hammer is an arm 98 carrying anti-friction rollers 99 against which bears a mainspring 100. The hammer further carries a sear engaging dog 101 which is caught by a sear 102, the latter being carried by the trigger 103, and being held in operative position by a suitable sear or trigger spring 10 1.

Projecting from the left hand side of the hammer is an arm- 106 which is disposed in the path of movement of a cocking lever 107 that is pivoted to the upper rear portion of the bar 27, and is held in operative position by a spring 108. The cocking lever fits within a recess in the bar, and has a rule joint connection therewith, so that during the rearward movement of the bar it will engage with the arm 106 for the purpose of moving the hammer back to cocked position. On the reverse .or forward movement, the spring 108 will yield, allowing the cooking lever to click over the arm 106 leaving the hammer unobstructed.

In order to prevent premature firing movement of the hammer in case the latter is not fully cooked by the lever 107, or in case of accidental pressure on the trigger before the parts are locked, provision is made for preventing movement of the hammer until the locking bolt 21 moves into full engagement with the groove 30.

Projecting rearward from one of the arms 34 of the locking bolt is an arm 110, to the rear end of which is pivoted a bell crank lever 111 free to move downward and rearward and locked from movement upward and forward by means of a lug 112. The forward end of the lever is engaged by a small leaf spring 113 which yields as the rear end of the lever is engaged by an arm 115 projecting from the right hand side of the hammer as the latter is moved to cocked position, this occurring before the locking bolt moves to the locking position, and in case the hammer starts on the firing movement before the bolt reaches the locking position, the arm 115 will engage the lever 111 and the hammer will be held from striking against the firing pin. The arm 11.5 is provided with a slot 116 arranged close to the side of the hammer, and in such position as to be opposite the lever 111 when the locking bolt moves to locking posi tion, as will be seen on reference to Fig. 5, so

that when the bolt assumes this position and the gun is in readiness for firing, the lever 111 will form no obstruction to the firing operation.

Projecting from the rear of the standing breech is a pin 120 forming a support for a small helical spring 121 that is in the path of movement of the hammer. This is a rebounding spring that serves after the firing operation to throw the hammer slightly back for the purpose of clearing the firing pin and preventing the latter sticking in the primer of the shell.

Arranged near the opposite edges of the standing breech are two extractors 125 and 126 arranged to engage the rim of the cartridge and fitting in. suitable grooves at the breech end of the barrel when the gun is in firing position. The extractor 125 engages the right hand side of the shell rim, and is in the form of a small lever, the rear end of which projects through the standing breech and is engaged by an operating spring 127. The extractor 126 is in the form of a spring arm that is provided with a projection 128, the latter being disposed in the path of movement of a cam lug 129 projecting from an ejector 130.

The ejector is carried by a rod 131 that is guided in a slot 132 in the plate 11, (Fig. 7), and the forward end of the rod is engaged by a lug 132 projecting from the side of the barrelwhen the latter has nearly completed its full forward movement.

In the operation of this portion of the mechanism, it will be understood that the extractors both normally engage the rim of the shell, while the ejector lies against the rear face of the shell. During the opening movement of the barrel, the extractors retain the empty shells, and when the breech endof the barrel has cleared, the forward end of the shell the lug 132 engages the forward end of the ejector rod, pulling the latter sharply forward. This movement causes the cam 129 to engage the lug 128 of extractor 126, pulling the latter sidewise to the position shown in Fig. 3, while the ejector throws the empty shell out, as indicated by dotted lines in Fig. 3.

The firearm is provided with a safety in the form of a bar 135 which projectsthrough a slot at the top of the frame and is provided with a thumb plate 136. The bar carries a rearwardly projecting arm 137 which may be engaged by a spring catch 13S carried by the frame, the catch being arranged to hold the safety either in operative or inoperative position. The lower end of the bar carries an arm or lug 1410 arranged to move directly over the trigger and prevent upward movement thereof, and is further provided with an arm 141 that projects into the path of movement of the sear engaging arm of the hammer, thus forming a double catch or safety that will prevent accidental discharging movement of the hammer.

The operation in brief is as follows :The parts being in the position shown in Fig. 1, the gun will be fired by releasing the hammer which strikes against the firing pin and discharges the cartridge. The marksman then pulls forward on the forearm 20, the first result of this movement being to engage the cam 41 of release rod with the roller 36 of the locking bolt, moving the latter to the right and out of the groove 30. By this time the rear walls of the slots 44 of the forearm engage against the rear ends of the lugs 43 of the barrel, and as the forward movement is continued, the barrel moves away from the breech block. The cam 74 of arm 27 engages the arm 71 of the carrier-and throws the carrier down from the position shown in Fig. 1 to the position shown in Fig. 2, and at this time the lug 132 of the barrel engages the ejector arm and pulls the same forward for the purpose of throwing out the empty shell which has been retained by the extractor during the forward movement of the barrel. The cam 60 then acts to move the pallet 55 to release position, and the magazine spring forces the rearmost cartridge out on to the carrier, while the pallet 56 prevents the passage of a second cartridge from the magazine. Immediately after the lever 46 moves from engagement with the roller 50, the spring 47 moves the forward end of said lever across the slot 48. On starting the return movement of the forearm, the release rod 40 engages the forward end of lever 16, and movement is transmitted therethrough to the bar 27 and arm 27.

The first effect of the movement is to release the cam 60 from the finger or pin 59, the cam 60 striking the finger 58 and restoring the pallet 55 to its initial position. At the same time or about the sametime, the cam shoulder 73 at the end of the flange 72 strikes against the forward end of the flange of the carrier, and the latter moves upward to the position shown in Fig. 1, carrying with it the shell, and the shell is received between the two extractors. As the rearward movement continues, the cam 84 at the bottom of the barrel engages the cam arm 83, thus raising the cartridge lifter arm 82, so that the forward end of the cartridge will be presented in position to enter the bore of the barrel, and during the further rearward movement of the barrel the shell will be fully entered therein.' As the movement continues to the rear, the cocking lever 107 will engage the arm 106 and move the hammer to cocked position, while the slightly inclined face of the bar 27 will force the locking bolt to release position, permitting the passage of the cam shaped end 41 ofthe release rod. When the barrel has moved to the full rearward position, the springs 37 will force the locking bolt into the groove 30 and the lever 111 will then be carried into alinement with the groove 116, so that the hammer will be free for the firing movement.

It is to be especially noted that the gun when in readiness for firing is of no greater length than the ordinary single shot or double barrel gun, inasmuch as the barrel is continuous from the standing breech to the muzzle, and there is no interval between the standing breech and the breech end of the gun.

In order to lower the hammer from cocked position without discharging the shell or cartridge, one side of the hammer is provided with an inclined lug 150 which may be caught by a pin 151 that extends through an opening in the side plate 12 and is normally held in the dotted line position shown in Fig. 5 by means of a spring 152, so that the lug will clear the inner end of the pin. WVhen it is desired to lower the hammer, the pin is forced in and then the trigger is pressed, whereupon the lug 150 will strike against the pin, and the movement of the hammer will be checked.

In order to permit taking down, the opposite sides of the inner walls of the receiver are provided with grooves 156 that are arranged for the reception of ribs 157 projecting from the sides of the rear portion of the magazine, as shown in Figs. 17 and 18. The two mem'- bers are held rigidly locked by screws 158 that pass through alining openings formed in the receiver and magazine.
